19 Claims.

This invention relates to new and useful improvements in aninterchangeable skate and shoe.

The invention has for an object the construction of an article asmentioned which is characterized by an arrangement wherein the skate maybe removed from the shoe when desired.

Still further, the invention particularly proposes to so construct thecombination of shoe and skate that the skate has an offset studrotatively engaged in a bayonet opening in the shoe bottom for theengagement and disengagement of these parts, and in addition, the skatehas a slide support and a catch for coaction with other portions of theshoe for firmly holding the skate in position on the shoe.

More particularly, it is proposed to construct the skate to be connectedwith a slide support adapted for engagement in a complementary openingextended in from one edge of the sole of the shoe in a manner so thatthe slide support assumes its operative position when the offset studpreviously mentioned is moved to its operative position in the bayonetopening.

Still further the invention proposes the provision of a catch engageablewith a portion of the shoe bottom to hold the skate fixed againstrotative disengagement as expressed in the previous paragraph.

Still further the invention proposes the construction of a device asmentioned which is simple and durable and which can be manufactured andsold at a reasonable cost.

For further comprehension of the invention and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying "drawing and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of my disclosure:

Fig. l is a side elevational view of an interchangeable skate and shoeconstructed according to this invention.

Fig. 2 is a bottom view of Fig. 1.

Fig. 3 is a perspective view of the shoe and skate but illustrated withthe skate partially disengaged.

Fig. 4 is a, fragmentary enlarged sectional view taken on the line 4-4of Fig. 2.

Fig. 5 is a fragmentary enlarged sectional view taken on line 55 of Fig.2.

Fig. 6 is a perspective view of the skate per se.

The interchangeable skate and shoe, according to this invention,comprises a shoe I II having a shoe bottom II comprising a sole portionIla and a heel portion Ill). The interchangeable skate associated withthe shoe comprises a skate knife, blade or runner I2 having a stud I3attached near its rear end and formed with an 5 offset head or couplingelement I4 adapted for rotative engagement in a bayonet opening orsocket I5 formed in the heel portion Ilb of the shoe. The bayonetopening I5 comprises an elongated opening I50 longitudinally of the heel10 and communicating with an interior enlarged opening I5b in such amanner that the stud I4 may be inserted first through the opening I5ainto the opening I5b and then rotated to assume a crosswise position asillustrated in Fig. 2. The 5 side walls of the interior opening I5b arecovered with metal reinforcing strips I50 and I511. A pair of staples I6are engaged through the material of the heel portion II b and limitturning of the head I4 to a position in which it is at 20 right anglesto the opening I5a.

The skate knife I2 is provided with a bracket I1 intermediate its ends,supporting a slide I8 in the form of a fiat arcuate element. This slideI8 is adapted to engage a receiving opening or 5 socket I9 formed in thesole portion I Ia of the shoe. This receiving opening I9 is ofdovetailed construction, that is, it has a restricted lower portionthrough which the bracket I1 may slide and an enlarged upper portion forreceiving the edges of the slide Ill. The opening I9 is reinforced withseveral metallic plates 20 and 2| arranged at the top and bottomthereof. The construction is such that the slide I8 works against themetallic parts 20 and 2I and not 35 against the leather or othermaterial from which the sole is constructed.

The skate knife I2 is provided with a conventional front post 22. Thisfront post is equipped with a catch 23 adapted to hold the front of theskate upon the front of the sole portion. More particularly, the catch23 comprises a catch bolt 23a pivotally mounted at the point 24 upon thefront rod 22 and formed at the top with a hook portion 23b adapted toengage a receiving opening or socket 25 formed in the front portion ofthe sole. The lower end of the catch bolt 23a is formed with an undercutportion 23e adapted to engage the front end of a retaining leaf spring230. This retaining spring is fixed at one end upon the upper portion ofthe skate knife I2 and normally tends to assume a raised position so asto automatically engage the undercut portion 232 to hold the catch inthe operative position.

In Fig. 1, the catch 23 is shown in the operative 55 position with thespring 230 holding it in this position. To move the catch intoinoperative position, it is first necessary that the front end of thespring 230 be depressed and then the catch bolt may be pivoted to aposition illustrated in Fig. 5 in which it is disengaged from thereceiving opening 25. The receiving opening 25 is reinforced with ametallic insert 21. The catch bolt 23 is formed with a central slot 23dso as to be adapted to engage over the front rod 22 of the skate knife.

The operation of the device is as follows: To remove the skate from theshoe, the catch 23 should first be disengaged and then the skate rotatedabout the stud I3 so as to disengage the slide support 18 from theopening l9 and furthermore, so as to move the head I of the stud to alongitudinal position, in which position it may be removed from theopening l5a.

While I have illustrated and described the preferred embodiment of myinvention, it is to be understood that I do not limit myself to theprecise construction herein disclosed and the right is reserved to allchanges and modifications coming within the scope of the invention asdefined in the appended claims.
